rPrauzcsmouivn APPARATUS.

Application led July 8, 1927. Serial No. 204.365.

hends a playground apparatus which includes a plurality of longitudinally spaced and con.

nected, transversely arranged units presenting horizontal climbing rungs extending both transversely and longitudinally of said apparatus.

The invention furtlierinorecomprehends in connection with an apparatus as previously set forth, a sliding member supported by said units and disposed at a longitudinal inclination and to which access may be gained at v various levels by virtue` of tlieseveral .units and their connections. The invention furthermorev coinprehends a playground apparatus composed of units and connections therebetween which may be transported in a knockdowncondition and readily erected or set .up at the point of use. The invention furthermore coinpreliends a playground apparatus which is extremely simpleyin its construction, inexpensive to manufacture, and which is highly etlieient for the purpose for which it is intended.

With the above recited and other-objects in View, reference is had to the following description .and accompanying drawings in which there is exhibited one example or enibodiment of the invention, while the appended claims define the actual scope of the invention.

In the drawings Figure 1 is a rear end'view of the apparatus;

Fig. 2 is a longitudinal sectional view thereof taken approximately on the line 2 2 of Fig. 1;

Fig. 8 is a face View of one of the interine diate units on a reduced scale.

Reterring to the drawings by characters of reference, 10 designates generally a unit of Which'there are a plurality transversely arranged and in longitudinally spaced relation. Each unit consists of an arcuate crown bar 11 of substantially semi-cireular formation. The crown bars are preferably of circular configuration in cross section and may be' either solid or of hollow pipe construction.'

Each unit further includes a pair of substani tially U-shaped supportingmembers 12, cach of which comprises a lower bight portion 13 and inner and outzcrupstanding legs 14 and 15, the former inner legs being of greater height than the latter end of the inner leg is threadedly engaged in the depending stem 1G ol' a substantially v T-shaped hollow coupling`17, through which the crown bar l1 extends; A set screw 18 is threaded through the coupling and engages the crown bar for locking the coupling in the proper position onthe crown bai. end of the outer leg l5 is connected to the terininal of the crown bar by a tubular union 19, which is intcriorly threaded to coact with the oppositely threaded ends 2t) and 21 ot' the leg 15 and the crown bar terminal. he units 1.0 when thus assembled are arranged in longitudinally spaced relation and connected and maintained in said relation by longitudinal rods 22 spaced equidistantly and vertically with respect to the inner and outer legs and around the outer periphery of the crown bar. The rods 22 are secured in place by U-bolts 23y having nuts 24. dinal rods 22 in addition to connecting and bracing the structure. also serve as climbing i'ungs. In addition to the longitiulinal rods, the structure is further braced transversely by transverse rods 25, which are likewise secured to the units by U-bolts 2G extending through apertures in the unit legs and fitted with nuts 27. A sliding member is supported by said units and disposed at a longitudinal inclination and said sliding member consists of laterally spaced side'strips 28, in the lower portion of which a plurality of rollers 29 aro journaled in close proximity to eachother. The rods 22 and 25 in addition to presenting horizontal climbing rungs, serve as a means The upper outer legs. The upper plurality of longitudinally for gainingaecess to the sliding member at Various elevations. Certain ot the transverse rods, designated by the reference character .25, are made 'in short length sections-which amount ot climbing space to satisfy the propensity ot' children to climb and which apparatus in addition is equipped with a'sliding device having a sliding surface which otlers a slight resistance and friction.

1. A playground apparatus, including a plurality ot. longitudinally spaced transversely arranged units, longitudiiuil and transverse horizontal conntfrting elements presenting climbing rungs extending transversely and longitudinally ot said apparatus, and a sliding member supported by said units and disposed at a longitudinal imflination.

2. A playground ammi-attrs, including a spared transversely arranged units, longitudinal and transverse horizontal connecting elements presenting climbing rungs extending transversely and longitudially of said apparatus, and a sliding member supported by said units and disposed at. a longitudinal inclination and to which access may be had at various elevations by virtue of the climbing ruugs.

3. A playground api'iaratus, including a plurality ol longitudinally spaced transversely arranged units, and longitudinal and transverse horizontal connecting elements presenting climbing rungs extending transversely and longitudinally ot said apparatus, said units each consisting ot an arcuate. crown bar and a pair ot substantially U-shaped supporting members, each ol which comprises a lower bigh't portion and inner and outer legs, the former being o'l greater height; than the latter and connected to the crown bar adjacent its central higher point. and the latter outer legs connected to the tern'iinals ot the crown bar. j

4. A playground apparatus, including a plurality of longitudinally spaced transversely arranged units consisting otv an arcuate crown bal and a pair olf substantially U-shaped supporting members, each of which Acomprises' a lower bight portion and inner and outer legs, thelormer being ot' greater height than the latter and connected to the crown bar at its central higher point and the latter connected to the terminals ot the crown bar, transverse horizontally arranged Vertieally spaced elements connected to the legs of said units and horizontally disposed longitudinal elements connected to the inner and outer legs and to the crown bar in equidistantly spaced relation.
